As used in this disclosure, a “charging voltage” is an electrical flow at a predetermined voltage and/or current which may be constant or variable. This electrical flow of electrical charge facilitates an increase in stored electrical energy of an energy storage device, such as without limitation a battery

With continued reference to FIG. 1 , in some embodiments, charging voltage 148 may be provided in a plurality of phases or stages to optimize charging of energy source 156 and/or battery 152. Each charging phase or stage may have a prescribed and/or optimized charging voltage and/or current which may be variable or constant. Any number of charging phases or stages may be utilized, as needed or desired, with each including a prescribed and/or optimized charging voltage and/or current. In an embodiment, a first charging phase may include a constant current which is provided for charging or recharging of energy source 156 and/or battery 152. In an embodiment, a second charging phase may include a constant voltage which is provided for charging or recharging of energy source 156 and/or battery 152. In an embodiment, a third charging phase may include a constant current which is provided for charging or recharging of energy source 156 and/or battery 152. This constant current (or second constant current) in the third charging phase may be different from or the same as the constant current in the first charging phase. In other embodiments, additional charging phases may be efficaciously utilized, as needed or desired, giving due consideration to optimization of charging or recharging of an energy source and/or one or more batteries. Controller 104 and/or charging connector 108 are, in some embodiments, configured to optimize charging or recharging as a function of the charging phase by receiving voltage datum 144 and optimizing charging voltage 148 transmitted to aircraft 136.

Still referring to FIG. 1 , in some embodiments, charging voltage 148 may be provided to electric aircraft in three phases or stages including a first stage or bulk charge stage in which a constant current is provided for charging or recharging, a second stage or absorption charge stage in which a constant voltage is provided for charging or recharging, and a third stage or finish charge stage in which a constant current is provided for charging or recharging. This constant current (or second constant current) in the third stage may be different from or the same as the constant current in the first stage.

Still referring to FIG. 1 , bulk charge is generally a first state of charging. In this stage a battery or batteries are at a low state of charge (SOC), typically less than 80% full. In the bulk charging stage, the charging current is held constant to put as much amperage into the batteries as possible. As the batteries collect electricity, the voltage rises over time.

Still referring to FIG. 1 , absorption charge is generally a second stage of charging in which the charging voltage is held constant. Once the batteries reach a programmed “absorb voltage,” the batteries will go into the absorb stage. Typically, when a battery reaches this stage it is around 80-90% full (or charged) depending on the charge rate. During this stage, the batteries are kept at the programmed voltage, and the amperage going into the batteries reduces as the batteries become more charged. The absorb stage ends after a programmed time is reached or the number of amperes going into the battery falls below a preset number.

Still referring to FIG. 1 , finish charge is generally a third stage of charging in which the charging current is held constant. In some instances, the third or final stage of charging may include a float charging stage in which the charging voltage is held constant. Upon the completion of the absorb stage or finish stage, controller may drop the voltage to a preset value and begin a float stage. The batteries achieve float stage when they are at full or almost full charge. The float charge stage maintains a cell or battery in a charged condition by continuous, long-term, constant voltage charging at a level sufficient to balance self-discharge.

Still referring to FIG. 1 , in some embodiments, an equalization charging stage may be utilized. Equalization may involve a controlled overcharge that is done on a periodic basis. This may maintain battery at full charge and compensate for any self-discharge over time.

Continuing to refer to FIG. 1 , controller 104 is configured to monitor, regulate, control and/or optimize any of the charging phases or stages of energy source, such as, energy source 156 and/or battery 152. Controller 104 may be configured to monitor, regulate, control and/or optimize charging voltage 148 which may include, without limitation monitoring, regulating, controlling and/or optimizing voltage and/or current as provided to energy source, such as, energy source 156 and/or battery 152 during each charging phase or stage.

For example, and without limitation an energy source including one or more battery packs, battery modules, battery units, batteries, cells, or battery cells, and the like.

Still referring to FIG. 1 , in some embodiments, one or more sensors communicatively connected to energy source 156 and/or battery 152 may provide voltage datum 144.

For example, and without limitation, energy source may be configured provide energy to an aircraft power source that in turn that drives and/or controls any other aircraft component such as other flight components. An energy source may include, for example, an electrical energy source a generator, a photovoltaic device, a fuel cell such as a hydrogen fuel cell, direct methanol fuel cell, and/or solid oxide fuel cell, an electric energy storage device (e.g., a capacitor, an inductor, and/or a battery). An electrical energy source may also include a battery cell, a battery pack, or a plurality of battery cells connected in series into a module and each module connected in series or in parallel with other modules. Configuration of an energy source containing connected modules may be designed to meet an energy or power requirement and may be designed to fit within a designated footprint in an electric aircraft.

In an embodiment, and still referring to FIG. 1 , an energy source may be used to provide a steady supply of electrical flow or power to a load over the course of a flight by a vehicle or other electric aircraft. For example, an energy source may be capable of providing sufficient power for “cruising” and other relatively low-energy phases of flight. An energy source may also be capable of providing electrical power for some higher-power phases of flight as well, particularly when the energy source is at a high state of charge (SOC), as may be the case for instance during takeoff. In an embodiment, an energy source may be capable of providing sufficient electrical power for auxiliary loads including without limitation, lighting, navigation, communications, de-icing, steering or other systems requiring power or energy. Further, an energy source may be capable of providing sufficient power for controlled descent and landing protocols, including, without limitation, hovering descent or runway landing. As used herein an energy source may have high power density where electrical power an energy source can usefully produce per unit of volume and/or mass is relatively high. “Electrical power,” as used in this disclosure, is defined as a rate of electrical energy per unit time. An energy source may include a device for which power that may be produced per unit of volume and/or mass has been optimized, at the expense of the maximal total specific energy density or power capacity, during design. Non-limiting examples of items that may be used as at least an energy source may include batteries used for starting applications including Lithium ion (Li-ion) batteries which may include NCA, NMC, Lithium iron phosphate (LiFePO4) and Lithium Manganese Oxide (LMO) batteries, which may be mixed with another cathode chemistry to provide more specific power if the application requires Li metal batteries, which have a lithium metal anode that provides high power on demand, Li ion batteries that have a silicon or titanite anode, energy source may be used, in an embodiment, to provide electrical power to an electric aircraft or drone, such as an electric aircraft vehicle, during moments requiring high rates of power output, including without limitation takeoff, landing, thermal de-icing and situations requiring greater power output for reasons of stability, such as high turbulence situations, as described in further detail below.

Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various devices of components that may be used as an energy source.

Still referring to FIG. 1 , an energy source may include a plurality of energy sources, referred to herein as a module of energy sources. A module may include batteries connected in parallel or in series or a plurality of modules connected either in series or in parallel designed to deliver both the power and energy requirements of the application. Connecting batteries in series may increase the voltage of at least an energy source which may provide more power on demand. High voltage batteries may require cell matching when high peak load is needed. As more cells are connected in strings, there may exist the possibility of one cell failing which may increase resistance in the module and reduce an overall power output as a voltage of the module may decrease as a result of that failing cell. Connecting batteries in parallel may increase total current capacity by decreasing total resistance, and it also may increase overall amp-hour capacity. Overall energy and power outputs of at least an energy source may be based on individual battery cell performance or an extrapolation based on measurement of at least an electrical parameter. In an embodiment where an energy source includes a plurality of battery cells, overall power output capacity may be dependent on electrical parameters of each individual cell. If one cell experiences high self-discharge during demand, power drawn from at least an energy source may be decreased to avoid damage to the weakest cell. An energy source may further include, without limitation, wiring, conduit, housing, cooling system and battery management system. Persons skilled in the art will be aware, after reviewing the entirety of this disclosure, of many different components of an energy source.
